It’s a riot of colors, a kaleidoscope of different shapes and designs and, moreover, customization and imagination. What Detroit once thought up, a number of automotive artists have improved on, with sculpted tail light housings, recessed door handles (or no door handles at all.)

It’s the Goodguys summer car show at the Alameda County Fairgrounds, where more than 2,500 cars of all stripe and origin (mostly American) will be gathering, a place where you can wander from an inky, dark blue convertible to a luminescent green pickup truck.

This year, the show is featuring the 50th anniversary of Ford’s Mustang and there will be 50 of them to look at.

The show runs Saturday (8 a.m. to 5 p.m.) and Sunday (8 a.m. to 4 p.m.), May 31 and June 1, at the fairgrounds, 4501 Pleasanton Ave., Pleasanton, Calif.

General admission tickets are $18; children (seven to twelve), $6; six years old and under, free. Parking is $8. More information here.
